  Don't confuse XML, DTD and XSLT because they are different things (even
though related to each other).

  DTD defines the valid syntax of a certain XML-type file. For example, if
you want to define the valid syntax for a MathML or an XHTML file, you use
a DTD file for that. It defines which tags (and hierarchy of tags) and
their attributes are valid.

  XSLT is a stylesheet language for XML-type files. It tells how to
convert the XML file to something else (eg. to HTML so that a browser
can show the XML file). In other words, it defines how the XML file
should be shown.
